To all whom it may concern:

Be it known that I, FRIEDRICH WmKnN's,

av subject of the German Emperor, andre Carrying Linoleum intoInlaid-Linoleum justed' by means of change speed gear tov Presses, ofwhich the following is 'a's'peci fication.

This invention relates to mechanically driven devices for feeding thesupporting fabric together .with the loose. linoleum mass appliedthereon in the forin of a pattern to inlaid linoleum presses. v

It was heretofore customary for thesupporting fabric together with theloose linoleum mass applied thereon to be fed forward to the inlaidlinoleum press either by hand or byrmeans of a motor e. mechanically. Inboth cases the supporting-fabric could not readily be fed an exactlypredetermined distance, nor was it possible to main the hourly capacityat a maximum, because in the one andin the other case the feed wassubject to the estimate of the operator both as to the speed and theintervals at which it was to take place. I

A primary object of this invention is to obviate these disadvantages andto secure not only a uniform feed of the supporting fabric, but alsotorender the feed independent of the judgment of the operator.

To this end, according to one form of my invention 1 provide a remotecontrol time switch which closes the circuit ot'the magnet ofanautomatic starter and thereby connects into circuit the driving motorfor the feed of the web 'of fabric. A quickb'reak switch is-therebydriven by the feed roll of the fabric; this'switch can be ad;

various lengths of feed and releases the electromagnetof the automaticstarter by means of the remote control time switch whose clockwork itsimultaneously winds up. An electromagnetic brake connected in shuntprovides or the motor stopping as rapidl as. possible. At various parts"of, the table for the inlaid work are provided press" switches whichenabled-he operator to prevent the motor starting early. At the timeswitch is provided in addition a show.

cit-uniting switch for allowin" the motor to run cont nuously when a waredmp belt of jute is to be replaced and a new supportin fabr'ieis to bedrawn in.

According to another form of the inventionthe driving motor is cut intoand out of circuit entire electrically in such a manner that the feedlength of the linoleum can be readily varied during the feedin operationand that the interval between t e stopping and restarting of the drivingmotor can be readily varied as desired durin the manufacture of the nextlength of amino. leum to be drawn forward. 4

Another improvement of this modification is the provision of twocontacts interpolated in the circuit of the driving motor. One of thetwo contacts is connected with the press stamp and the other with thepat- LIND- if the press stamp and the pattern lifting frame rest uponthe linoleum. Therefore,

.the motor circuit can only be closed when both the stamp and also theframe are lifted from the linoleum.

In the accom anying drawin Figures 1 (to 4 and Figs. 5 to 9 show twolllustrat-ive embodiments of the invention by Way of example. Fig. l is'a top plan view showing the "en'eral arrangement of the plant accordmgto the one embodiment, Figs. 2 and 2 are front andend elevation,respectively,

showin the quick-break switch connected with a change speed gear, Fig. 2shows a detail of Fig. 2. Fig. 3 is a diagram of conmotions and Fig: 4shows the remote'control time switch in elevation. Fig. 5 is a top.

plan view showing the general arrangement of the entire plant accordingto the second embodiment, Fig. 6 is a diagram of connections, and Fig. 7vshows the time switch for to ping the driving motor in elevation; Fig 8shows, enlarged, the switch mechanism comprised in the diagram Fig. 6,and

Fig. 9 is aside elevation of the driver for the contact which limits thefeed of the web of fabric.

Referring firstly to Figs, 1 to 4,, the drive of the feed roll for theconveyor belt a" carrying the web of fabric isbrought about by 'a remotecontrol time switch a of any desired "construction (Figs. 1 and 3) whi hcloses the circuit of the electromagnet of an automatic starter 6 overan electric resisttime b" 120th of knownconstruction by which thedriving motor an started. ,4

45 I which is clamped a leather .ring displaceremote control timeofclockwork mechanism by means of a lever a whose one arm carries a pawla coacting with the teeth of a ratchet a fast OIlrthG shaft of the firstdriving wheel a. The other arm of the lever a is formed as a toothedsector in which meshes a second toothed sector constituting the end ofone arm of a bell-crank lever a". The other arm of this bell-crank levercarries the armature a of the electromagnet a which is- :connecteclwit-h the hereinafter described quick-break switch and attracts itsarmature -when the quick-break switch is closed. The glever a? isthereby rocked upward by means of. the two toothed sectors and the a'is' tensioned. The latter then acts by means of the pawl a on theclockwork mechanism whose pendulunrbob a is adjust-able,-in order thatthe time which the clockwork requires until it has run down oruntilthe'spring a is distensioned may be adjusted as desired. This timeswitch a comprises two contact pieces I), b which are apart while theclockwork is working and are'connected to the coil of the magnet of theautomatic starter b. When the clockwork has almost run down the lever ais in the position shown in full lines in Fig. 4 and under the influenceof the spring a presses together the two contact pieces 6'. W. Thecircuit of the .coil of the magnet of the automatic starter Z) isthereby closed and the driving motor 0 started. This motor 0 drivesthefeed roll i-through the medium of a. clutch d, worm gearing e, thecountershaft f and spur gearing g, h. The shaft of the feed roll 2'carries a sprocket wheel Icprises any desired suitable change speed gearconsisting, for example. of two adjacent conical rollers n, n, (Fig. 2)between abie longitudinall of the rollers by means shaft n of a manuallydriven screw 0'. so that the rotation of the one conical roller 71. isim-' parted by the leatherring a to the other roller n Keyed on the. oneend of the of'the roller 91. is an arm 72, having a slanting face p,(Fig. 2 and loose on the same end of the -shaft is a collar ;0composedof insulation havinglet into one part of its periphery a contactpiece 72 (Fig. 2). Against the periphery of thecollar pslide twoinsulated contact springs p, p which are connected with the coil of theelectromagnet a of the remote control time. switch a. (Fig. 4). Thecollar 39 is connected with the one end of a springp whose other end issecured to the shaft 71". Below this shaft is mounted a spring-pressedbolt 72' which generally projects so spring contact pieces 5', 6

far toward the collar 7; that the stop 32? carried by the latter bearsagainst it, so that the collar is locked and cannot rotate with theroller 12. (see Fig. 2 dotted lines). In this position the two contactsprings bear on the insulation of the collar p, as shown in Fig. 2 infull lines so that no current can flow through them. The bolt p has anotch which coacts with the slanting face p* of the arm 7;". Now whenthe roller n rotates, the spring 17' connected with the collar p istensioned because the collar cannot rotate owing to its being held bythe bolt p. After about one rotation of the roller '21, the face 3; ofthe arm 7) pushes the bolt 7) backward, so that the collar 7) isreleased and under the action of the spring 79 rotates approximately onerevolution, its contact piece 19 electrically connects together the twocontact spring 7), p for a short time, so that the electromagnet a ofthe remote control time switch connected therewith is energized, theclockwork is wound up and the spring a is tensioned. Simultaneously, the(Fig. 2) are separated. The circuit of the automatic starter b isthereby broken, so that the circuit of the motor a and, simultaneously,that of a braking magnet q. of known construction which influences thehand brake 1' (Fig. 3) is broken. The hand brake is applied and themotor 0 at once stops. The outer casing of the clutch between the motor0 and the worm gearing e (Fig. 1) may serve as the brake disk.Immediately after the collar 7) is released the bolt p" is likewisereleased by the arm-p and snaps back so that it again locks the collar7).

After the elapse of a predetermined time controlled by the time switchthe latter, whose clockwork was wound up when the drive of the feed roll5 was stopped by the quick-break switch 1), switches the automaticstarter 6 into circuit again, whereby the braking magnet (7 is againenergized and the band brake 7' released. The motor 0 also startssimultaneously. 'The play is'then repeated afresh. As long as the motorruns the conveyor belt 6' is driven and the jute fabric on the belt andthe loose linoleum mass applied on the jute fabric are fed under thepress.

It is obvious that the speed of the feed and of the change of theinterrupted drive of the conveyor belt z" can be adjusted at the timeswitch a and at the speed change 9%, n as desired within certain limits.

' Referring now to Figs. 5 to 9, the gen eral arrangement of the drivingmechanism fort-he feed of the web of fabric of the second illustrativeembodiment is substantially the same as that described above. A conveyerbelt 5 for carrying the web of fabric having the linoleum mass to beapplied thereon runs over rollers z, of which that gearh meshing with apinion 9 whose shaft f is driven through the medium of worm fgearinge bythe driving motor a when the brake 1' is released bya magnet q.Connected in series with the motor a is an automatic starter I)connected with the switch:

gear a in the manner which will now be described. This switch gear amaybe ar ranged in various ways, 6. g. as in Fig. 8. A switch lever 2,carrying an armature 2', and able to rock about a pivot 1, is under theinfluence of two electromagnets 3, 4 and carries at its free end apieceof insulation 2 The latter carries two pairs' of wiping springs 5 and 5,the two springs of each pair being connected together. Two stops 6 and 7limit'the range of motion of the lever 2; On' the one side in thedirection of osc-illation of the springs 5, 5 are contact pieces 8, 9'and 10, 11 and on the other-side contact pieces 12, 13 and 14, 15. Ofthese, the contact piece 8 is connected with the electromagnet 4 (Fig.6) and the cont-act piece 12' with the electromagnet- 3. The twoelectromagnets 3, 4 have a common return conductor 16. Thevconltactpieces 11'and 15 are connected to the feeders. The contactpiece 10 leads to the automatic starter b of the motor 0. In the circuitof the contact piece 10 to the automatic starter b are interpolated twocontact pieces 17, 18, each of which possesses a weighted lever .17 and18', respectively, tending to keep the contact open. These weightedlevers are located in the range of motion of stops at, y of the pressstamp 00, and of the frame y, respectively, each of which in its raisedposition closes its contact. The contact 9 leads to a feedlimitingcontact 19 provided on the press. 00 (Figs. 5 and 6). The contact 14leads to an auxiliary motor 2 of a remote control time switch which isshown by itself in Fig. 7 and possesses three switch drums 20, 21, 22fast on the same shaft 31. Each of'these three drums is wiped bV twocontact springs 23 and 24, 25 and 26, 27 and 28, respectively. Of these,the springs 24, 26 and 28 are connected to a common return conductor,while the spring 23 leads to the contact piece 13 of the switch gear (1(Figs. 6 and 8') and.

the spring 25 to the auxiliary motor 3. In

addition, a return conductor 11-, in which is interpolated alamp-resistance 10. branches off from the line between the motor .2thespring 25. A call bell t-is in'ter -)olated inthe line connecting thespring 27 with the feeder.

I ing 3Q" to the shaft 31. The two switch The time switch'driven by theauxiliary motor 2 (Fig. 7 )"isarranged as follows:''

The auxiliary motors directly or indirectly drives the pulley 29 whosemotion is speeded -down and tr-ansmitted by means of double worm-wheelearing contained in] the caspcaasc drums 21and 22 are fast on thisshaft;

Each of the drums possesses only at oneipart.

cf'i'ts periphery a contact piece. for connectmgthe spr ngs 25-,26.and{27, 28, res ectively. Fast on the-shaft ,1 is not on ya disk 32,carrying'a stop 33, ut also anfarm p havlng a slant ng face 7), whilethedrum 201s looseon the shaft 31.- The rim of the drum 20 is connectedwith" the one-end-of a.

spring p whose other end is secured to the shaft 31. A spring-pressedbolt p is guidedunder the latter in the frame 34 and the bolt I pgenerally projects so farthat the detent p of the drum 20 bears againstit, as shown in dotted lines in Fig. 7, so that the drum 20cannotparticipate in the rotation of the shaft 31. In this position thetwo springs 23, 24 bear on the insulated part of the drum 20, so that nocurrent can flow to the electromagnet 3 of the switch gear a (Figs. 6and 8). The bolt p has a recess which coacts with the slanting face 1*of the arm 72 The arrangement and motion of the drum 20 correspond tothose of the quickbreak "switch ofthe form described-above withreference to Fig. 2. When the shaft 31 rotates the spring]; mountedthereon and connected with the drum 20 is first tensioned, because thedrum 20 cannot rotate as it is held by-the bolt 17'. After the shaft 31has rotated almost... one revolution the face 12 of the arm p pushes the'boltp back so that the latter releases the detent p and the drum 20.This drum is then driven around almost one revolution under a pin 38which is within the reach of the stop 33 of the disk 32. As the drum 2Qrotates only when the shaft 31 has already rotated almost onerevolution, the stop 33 leads as much in front. of the pin 38, and thusadmits if almost a complete revolution of the drum 20. The face p of thearm 72 has such a position that is-releases the bolt 7) immediatelyafter the release of the drum 2O inorder that it can 'fly back and againlockthe drum '20. Y' The described apparatus operates as followsz-As'sumingthat the switch lever '2 its pairs of springs 5 and 5 hridgethe con-. tact. pieces 8,9 and "10,11.

"The bridging of the contact pieces 10,11 by the pair of springs 5' bringsxabout the connection in-circuit ofthe automatic starter 1), whereby the motor 0 is started while themagnet 9 simultaneously releases thebrake r. The motor a can, however,start only when the weighted lever 17 arranged in front of the hydraulicpress a: is lifted and closes the contact 17 and,also, only when theframe y by lifting the weighted lever 18 has closed the contact 18. Thelatter contact is a special means of security to prevent the motor 0from being started, if the frame 1 together with templets resting on itafter having been filled with linoleum I is not lifted from the part ofthe length of linoleumv having been just prepared to be drawn under thepress. Owing to the motor 0 being driven the feed rolls i are driventhrough the medium of the transmission e, f, g, h. and the length oflinoleum is fed under the press :22. The drivers is placed back on thelinoleunr a distance equal to that which the linoleum is to. be fedfor-. ward. When the required length of linoleum has been pulled underthe press the driver 8 abuts against the contact piece 19 and closes itscircuit, so that the electromag-' net 4 is'energized and pulls theswitch lever Con- 2 over into its right-hand position. sequently, theconnection between the contact pieces 8, 9 and 10, ll is broken andinstead thereof the contact pieces 12, 13 and 14, 15 are respectivelyconnected together. The electromagnet 4 is deenergized, the brake r isapplied as the magnet 9 becomes the motor 0. Owing to the contact pieces.14 and 15 being connected the\auxiliary motor a is. connected incircuit and drives the shaft 31. When this motor first starts thesprings 25, 26 are. still resting on the contact piece of the drum 21,and consequently this motor 2 obtains current directly for the purposeof overcoming its starting moment. Owing to the shaft 31 being driventhe drum 21 is also rotated until its contact piece slides away from thesprings 25, 26 and stops the direct supply of current for the auxiliarymotor a. For this motor there then remains'open only the circuit overthe lamp-resistance to, so that the speed of this tkmotor is slowedcorresponding to the numer of lamps in the circuit .for the. time be 1g. Obviously, by varying the resistance r and with it the speed of theauxiliary motor ans well as, of the drums 20, 21 22, the time betweenthestoppage and restarting of the motor 0 can be varied as desired. Insteadof a lamp-resistance any other kind of resistance may, of course, beemployed.

When the driver a has fulfilled its object namely actuating the contact19, it is place by hand back a distance equal to the next lengthof thefeed, in order that when the linoleum is next drawn forward it can op.-erate afresh.
